CARTON.

' full, clear, and exact description thereof,

reference being had to the accompanying drawings, and to the letters of reference specification.

This invention relates to an improved carmarked thereon, which form a part of this ton for crackers, biscuits and like articles of merchandise of that kind consisting of a single piece or blank of paper or fiber-board, provided with flaps and adapted to be folded to form the body of the carton, and a flexible lining sheet of paraflined or water proof paper, which is interfolded with the blank which .forms'the inclosure, and is designed to protect the contents of the carton from access of moisture thereto.

The invention consists in. the matters here inafter pointed out and set forth in the appended claims.

In the accompanying drawings Figure 1 is a face View of the end portion 7 of the blank which forms the body of the carton; Fig. 2 is a perspective view of one end of the blank and lining sheet, when thefront andrear walls of the blanks are folded at right angles to its bottom wall, and 1ts end flaps are unfolded; Fig. 3 is a perspective view of the same parts, with the end flaps on the front ,wall, withthe associated portion of the lining sheet folded inwardly; vFig. 4 1s a like perspective view, showing the end flaps on both the front and rear wa1ls of the carton after being folded inwardly, with the end flap on the bottom wall stillunfolded;

Fig. 5 is a perspective View of the end of the carton, with all of its end flaps folded 1nwardly to form the complete end wall of the carton; Fig. 6 is a horizontal section taken through the infolded end flaps of the carton,

with the adjacent parts of thelining sheet,

taken on line 6-6 of Fig. 5.

I As shown in said drawings, the sheet or blank (Fig. 1) from'which the carton 1s formed embraces four COIIIIBCtGdSBCtlOIIS A,

. B, C and D, which are'joined to each other along longitudinal parallel folding lines 1, 2 and 3, and of which the section A forms the front wall, the section B, the bottom wall,

.vided with extensions, constituting flaps A,

B and C which, when folded together, form the end wall of the carton. The upper edges of the end flaps A and C alinement with the upper, longitudinal margins of the front-wall and rear-wall sections A and C, while the bottom margins a and c of said end flaps are preferably inclined upwardly towardthe free ends of said flaps. The end flap C is shown as provided on its upper margin 'with a laterally or upwardly projecting flap-C which is folded inwardly over the open top of the body of the carton, as common in cartons of this general character. The flap B on the bottom B is preferably tapered on its side edges. In the interfolding of the said end'fiaps, to form the end wallof the carton, the front-wall and rear-wall flaps Aand C are first folded in are preferably in overlapping relation, and the bottom-wall flap B is-then folded upwardly outside of the said flaps A and C. When the said end flaps are thus inter-folded, the same-are secured together by a fastening device passing through the same; such fastening device, as shown, consisting of a metal staple F.

The lining sheet G of ,paraflined paper or the like, is made approximately the same in external dimensions as the connected sections of the carton-with theirend flaps. The said lining sheet is applied to, or against the inner surfaces of the carton sections A, B and C, with its lateral marginal part adjacent to the end flaps, A, B and C, and interfolded with the latter. The said lateral,

marginalpart of the lining sheet is so inter-,

folded with the end flaps, that one infolded part of'saidsheet rests against and covers the inner face of the completed end wall, another part of said lining sheet is located between the innermost and intermediate end fiaps, whi'le another part'of said lining sheet is located between the intermediate and ex-- ternal end flaps. The fastener F, by which the said' end flaps are secured together,

passes, or is inserted, through the marginal part of thelining sheet, Whichis folded between the innermost and intermediate flaps,

so that this'portion of said lining sheet is and covers the inner face of the end wall being left free or unattached to said end wall,

- margins by the interfolded end flaps.

Figs. 2, 3, 4 and 5 of the drawings illustrate the'manner in which the end'flaps and the adjacent marginal portion of the lining sheet may be interfolded. As shown in Fig.

.2, the front and rear walls or sections of the carton havebeen bent upwardly at right angles to its bottom wall, the end flaps of the carton are in extended position and the lining sheet rests in place with its front and rear margins extending upwardly in the plane of, and above the front and rear walls or sections of the carton. The partsbeing 1n the position described, the front-wall flap A except so far as it is held or confined at-its is' folded inwardly to the position shown in Fig. 3, carrying with it-the marginal part GT of the lining sheet beneath it. When the part G is thus foldedinwardly, an: oblique fold g is formed byrthe folding upon itself of the part G of the lining sheet, which rests upon the bottom-wall flap B. The rear-wall flap C is then folded inwardly, as seen in Fig. 4:, thereby carrying or folding the portion G of the lining sheet, inwardly against the outer face of'the front-wall flap A. As the part Gr ofthe. lining sheet is thus folded inwardly, the part G of. said in readiness for the lining sheet will be firmly held or confined at both ends of the carton, so that it cannot be displaced in handling the carton, or byany force that it may be necessar to apply to the lining '70 sheet during the lling operation; After the carton and its lining have been set .up,

.the end flaps secured, as shown in Fig. 5,,

and the contents of the carton inserted therein,'the upper margins of the lining 75.

sheet at the front, rear and ends of the carton, will be folded inwardly or downwardly in the particular manner or order stated;

the principal feature of my invention,being the interfolding of parts, of the lining sheet between the three end flaps, which are secured together by a fastener extending 90 lining sheet is again folded upon itself, on-

a second oblique folding line g. completion of this second fold, the part'G 'of the lining. sheet is folded into the form of a triangular tongue or flap, as shown in Fig. 4, which 'fiap projects-outwardly from beneath the lower edge of the flap C 4 and rests on the flap B. The said flap B is then folded upwardly against the fl [p C, and the triangular folded part G: o the lining sheet, is thereby folded between said flaps B and C. The metalfastener is then inserted through the flaps and the part Gr of the lining sheet (Fig. 6), thereby securing these parts together. a Y Byreason of the interfolding of the triangularly folded part Gr with or between the 'flaps O and B, or intermediate and outer'flaps, the lower margin of the inner marginal part G of they lining sheet is so firmly confined or held in place, that it will not be displaeed during the operation of filling thecarton or inserting the contents of the same. It being understood that the At the marginal part G of the lining sheet is sea cured between the innermost and intermediate flaps A and C, by the fastener F, while the marginal part G of said lining sheet is secured or confined at its lower margin, or along the lower margins of the said innermost and intermediate flaps A and C, in the manner described it follows that when the body of the carton is set up and through the same, while the part of the linmg sheet which is inside of the completed 3 end wall is left unperforated, and is held'in 'place by the interfolding of the adjacent parts of the said sheet between said end flaps' Moreover, instead of the fastener consisting ,of a metal staple, any other form offastening device may be 'used, which is adapted for insertion through, and to firmly j om, the end flaps and the portion of the lining sheet interposed between saidend flaps.

A carton made as hereinbefore set forth not only hasthe advantage described, so far as the holding in place of the lining sheet is concerned, but it has the further advantage that the metal fastener used for rigidly connecting the end flaps is covered or protected by the inner fold of the lining sheet; and cannot, therefore, come in contact with the contents of the carton. From the foregoing description of a carton embodying my invention, it will be understood that the desired result will be ob. tained by such interfolding of the end ormarginal parts of the lining sheet with the three end flaps on the carton walls, that a single thickness of the lining sheet will rest against and cover the inner surfaceof the end Wall formed by the infolded flap, another si-nglethickness of said lining sheet will .be located between the innermost flap and the intermediate flap that is folded inwardly against the same, while a folded portion of the said lining sheet will be folded between the said intermediate flap and the 125,

through the same and passes through the not, therefore, desire to be limited to the particular features of construction illustrated, except as pointed out in the append ed claims.

' I claim as my invention:

1. A carton, comprising a blank provided 1 at its end with three flaps adapted to be folded inoverlapping relation with each other, thereby forming the end wall'of the carton, a lining sheet, one marginal portion thereof being folded inside of the innermost flap, another marginal portion being folded between the innermost and intermediate flaps, and an intermediate portion folded uponitself and folded between the intermediate and outermost flaps, said intermediate portion of the lining sheet being joined to the lower margins of said first mentioned portionswof said lining sheet, and fastening means extending through the interfolded flaps and said portion of the lining sheet be tween said innermost and intermediate flaps.

2. A carton, comprising a blank provided at its end with two side flaps and an intermediate bottom flap adapted to be folded upon each other, and a lining sheet within said carton having its marginal portion in Overlapping engagement with said flaps, a portion of said sheet in engagement with one of said side flaps being folded inside ofthe innermost flap, the other portion folded between said side flaps, andthe portion in engagement with the bottom flap being folded upon itself and folded between the outer side flap and said bottom flap, its lower margins being joined with the first mentioned portions of said sheet, and a staple inserted throughsaid flaps and the portion of the lining sheetbetween the side flaps.

In testimony, that I claim the foregoing as my invention 1 afiix my si ature in the presence of two witnesses, this 20th day of March A. D. 1913.
